What part of GIGO don't you understand?

What is this magical power people ascribe to computer models?

Garbage In, Garbage Out, is bad enough, but when you put in good data and get out garbage, why do people assume that a little tweaking of the model will help?

Computers are STUPID, people. They know not a single thing about the real world. They do EXACTLY what we tell them, and thus they cannot be ONE SINGLE BIT smarter than a person even at their best.

Something that gives you a result that is off by a factor of three is probably not a useful tool. Something that gives you a curve that is of the wrong shape AND off by a factor of three is JUNK. It is USELESS. YOU need to start over.

"Our computer models (which we've tweaked so much that they produce the 'correct' data from random numbers, not just the 'real' input) say this will happen. You need to change your life because of our models!"

So, how about this carefully collected hard data I've gathered that contradicts your model?

"No! It is a computer model! Data? We don't need no stinking data!"

There are times I wish that theoretical computing classes were mandatory. Then again, I also often wish that for logic, basic mathematics... there's actually quite a list.

Sigh.
